Pioneering the Future of Radar Systems & Wireless Communications Optimization with Synthetic Data on Demand

Ansys' high frequency structure simulator shooting and bouncing ray solver (HFSS SBR+) is a high frequency electromagnetic (EM) solver engine for modeling installed performance of antennas and signal propagation in large environments. Applications include integrated antenna performance on large vehicles and buildings (installed antenna), antenna-to-antenna proximity coupling effects, radar cross section (RCS) modeling for electrically large targets (monostatic & bistatic) and indoor/outdoor wireless channel modeling in dynamic, bespoke environments. HFSS SBR+ is an asymptotic high frequency electromagnetics solver. With complementary capabilities to full wave solvers, high frequency asymptotic solvers can efficiently and accurately solve electrically large problems that would be intractable for finite element method (FEM) or finite difference time domain (FDTD) solvers, for example. HFSS SBR+ is a hybridization of geometrical optics (GO) and physical optics (PO) with additional physics such as physical theory of diffraction (PTD) and creeping waves (CW) for PO current correction near surface discontinuities and curvature, respectively. Uniform theory of diffraction (UTD) rays are also used to paint PO and PTD currents in shadow regions of GO rays. By leveraging both algorithmic and hardware-based (Nvidia GPU) acceleration, engineers can obtain massive quantities of synthetic data in record time.
